No problem!

Yeah, dual booting Win and Lin is… basically a trap at this point, I first tried to do it over a decade now…

There really is no need anymore, beyond very specific uses cases, to run Windows at all.

Linux caught up and has now exceeded it in basically everyway, as Windows has also enshittified.

I would suggest you look into just switching your Deck over to Bazzite.

From a basic user stand point, it is highly functional and performant, gives you more flexibility and utilities than default SteamOS, and you can even set up a linux container as a dev environment to do linux dev stuff, use Bottles or something if you need something closer to a Windows environment.

Yeah, its still not gonna play those few, super hyped and marketed AAA games… but fuck em, they’re evil corpos, stop giving them your time and money.

And I just made another suggestion to you in another comment:

You want BF style game(play)?

TitanFall 2. Still alive, still alive, got a reverse engineered server browser and private servers, runs great on linux via Proton.
